12 Best Nonplastic Food Storage Containers of 2026

Ready to Break Up With Your Plastic Food Storage Containers? Here Are Some Alternatives

Unless you’re more organized than me, you probably have what I affectionately refer to as a “doom cabinet.” It’s a jumble of mismatched lids and old takeout containers. It’s not pretty, but I’ve also been reluctant to swap them out. After all, I grew up watching my grandmother routinely use old Cool Whip containers for storage. But as I’m learning more about microplastics exposure, I’ve started looking at those random plastic containers a little bit differently.

I knew that heating food in plastic containers wasn’t ideal. But what I didn’t know was that avoiding that may not be enough. “Even just storing food in plastic containers can cause microplastic migration into food,” says Lisa Erdle, PhD, a microplastics researcher, environmental chemist, and director of science and innovation at the 5 Gyres Institute. Even food stored in a refrigerator or at room temperature in a plastic container can still release millions to billions of microplastics (plastic particles less than 5 millimeters in size) and nanoplastics (particles less than 1 micron in size).

And what’s the big deal with microplastics? It’s important to note that more research is needed. However, some studies have found that microplastics could increase the risk of heart attacks and strokes, while others show that they could play a role in cancer development.

There are also concerns about the potential impact of microplastics on our endocrine system (which controls the creation and release of hormones throughout the body).

While the full impact of microplastics on the human body has yet to be determined, in the meantime, limiting your exposure may not be a bad idea. And one of the easiest places to start is with your food storage. Below we’ve listed our favorite nonplastic food storage containers.

Our Top Picks for Nonplastic Food Storage Containers

Best for Small Portions

Caraway Mini Food Storage Set

$145 at Amazon

Pros

  • Made with ceramic-coated glass
  • Sizes are optimal for snacks, sauces, small servings
  • Airtight silicone gasket on lids to prevent leaks
  • Comes with storage

Cons

  • On the pricier side for small containers
  • Not ideal for full meals or batch storage

Key Specs

  • Material: Ceramic-coated glass
  • Microwave safe: Yes
  • Dishwasher safe: Yes
  • Oven safe: Yes (up to 450 degrees F)
  • Freezer safe: Yes
  • Capacity: Two 2.6-cup containers, two 1.75-cup containers, magnetic storage organizer

If you’re the kind of person who makes just enough pesto for one or needs a cute container for a spoonful of leftover frosting, Caraway’s Mini Food Storage Set is a delightfully functional solution. These petite, ceramic-coated glass containers are ideal for snacks, sauces, and lunchbox extras — and unlike plastic snack cups, they’re oven and microwave safe (the lids are not, just FYI). I’ve used them for leftover burrito bowls and to tote around servings of grapes and trail mix.

I love how sturdy these feel — they have a real weight to them that makes them feel expensive. Which, to be clear, they are. They also aren’t ideal for full meal portions, so if you’re meal-prepping an entrée, you’ll probably want to look elsewhere. But they come with their own storage organizer (no more loose lids and stray containers!) — and, true to Caraway form, they are available in an array of pretty colors that you won’t be ashamed to leave out on your countertop.

stasher starter kit

Best Reusable Silicone Bags

Stasher Starter Kit 10-Pack

Pros

  • Dishwasher safe
  • Ideal for fridge, freezer, or on the go
  • Replaces hundreds of single-use plastic bags

    Cons

    • Can be tricky to dry completely after washing
    • Not easy to store neatly

    Key Specs

    • Material: Food-grade silicone
    • Microwave safe: Yes
    • Dishwasher safe: Yes
    • Oven safe: Yes (to 425 degrees F)
    • Freezer safe: Yes
    • Capacity: Varies by style (12 fluid ounces to 56 fluid ounces)

    Stasher bags are a reduced-plastic standby for a reason. Made from food-grade silicone, they’re safe for everything from freezer soups to sous vide to snack duty. The pinch-press seal holds tight, and the bags come in a huge range of colors and sizes, so whether you need something small enough to hold a sandwich or large enough for a big slice of leftover pizza, there will be a size to cover that.

    Of course, these bags do come with their challenges. You’ll want to be sure they dry completely after you wash them, and you may have to get creative to do so. My solution usually involves sticking a Stasher bag on top of my sink’s sprayer until it dries, though a drying rack (which Stasher also sells) would be a more elegant solution. These are also tough to store; I’ve taken to using a plastic file holder to keep them from meeting the same fate as some of my other food storage containers (see my intro). But my sets (I have two) have lasted through multiple dishwasher cycles and do a great job of keeping my food fresh. If you’re looking for a practical, zero-waste swap, this one’s an easy favorite.

    glass bakeware set

    Best for Oven-to-Table Meals

    Tupperware Voila Glass Bakeware Set of 3

    Pros

    • Oven safe up to 572 degrees F
    • Airtight lids for storage after baking
    • Three versatile container sizes in set; individual pieces available as well

    Cons

    • A bit heavier than standard containers
    • Plastic lids are not oven safe

    Key Specs

    • Material: Borosilicate glass
    • Oven safe: Containers yes, lids no
    • Microwave safe: Yes
    • Dishwasher safe: Yes
    • Freezer safe: Yes
    • Capacity: Three containers with lids (square 1.7 quart, round 1.8 quart, and rectangular 3.2 quart)

    Those colorful plastic sets of yore are getting a makeover with Tupperware’s entry into the world of glass food storage. Each piece is made from thermal shock–resistant borosilicate glass, meaning you can cook a casserole, let it cool, and pop that same dish right into the fridge. They’re great for batch meals, potlucks, or anyone who’s sick of transferring food into yet another container.

    Mine have been in regular rotation since Tupperware released this line a few months ago. While I have the three-piece set (which includes square, round, and rectangular containers), you can buy pieces individually if you’re short on space. These are heavy (the trade-off with choosing borosilicate glass over plastic), and while the containers themselves are oven-safe to 572 degrees F, the lids (which are plastic) are not. Still, if you’re looking to save some space in the dishwasher, these have proven to be extremely useful.

    Best for Freezing Broths and Sauces

    Souper Cubes Silicone Freezer Molds

    $78.99 at Amazon

    Pros

    • Designed for freezer use and easy portioning
    • Made from food-grade silicone
    • Great for stocks, sauces, baby food

    Cons

    • Not ideal for everyday storage outside the freezer
    • Bulky if you’re short on freezer space

    Key Specs

    • Material: BPA-free food-grade silicone, embedded steel frame
    • Oven safe: Trays yes (to 415 degrees F), lids no
    • Microwave safe: Yes, though it is not recommended
    • Dishwasher safe: Yes
    • Freezer safe: Yes
    • Capacity: Varies

    I was a chronic waster of that last bit of broth or that leftover pesto before I got these. Souper Cubes are made for freezing soups, sauces, and batch-prepped meals, and they make it convenient enough that you’ll actually follow through with your food-saving plans. The silicone trays are marked with measurement lines and reinforced with a steel rim for easy lifting, even when full. Since they’re bisphenol A (BPA)–free and designed specifically for freezer use, they’re a great alternative to plastic bags or takeaway containers — especially for high-fat or hot foods, which experts say may increase microplastic release. “Fatty and acidic foods are more likely to interact with the plastic,” says Dr. Erdle, “leading to increased leaching of additives like phthalates and bisphenols.”

    These shouldn’t be microwaved (due to that steel rim). They also take up quite a bit of space — picture a tray of cup-sized ice cubes, and you’ll get the picture. But with a huge variety of sizes available and a format that makes it easy to freeze everything from portions of soup to leftover dollops of tomato paste, they can be a very handy solution to a common food storage problem.

    glass container

    Best for Lunches

    W&P Seal Tight Glass Bowl

    Pros

    • Leakproof borosilicate glass
    • Microwave and dishwasher safe
    • Won’t absorb odors or stains

    Cons

    • Not oven safe (glass lid excluded)
    • May not be suitable larger meals

    Key Specs

    • Material: Borosilicate glass, BPA-free screw-top lid
    • Microwave safe: Yes
    • Dishwasher safe: Yes
    • Oven safe: No
    • Freezer safe: Yes
    • Capacity: 16 ounces (oz) or 24 oz

    If you want something a little classier for transporting your lunchtime salad, this compact glass lunch bowl is a minimalist alternative. The screw-top lid seals tight (yes, even with soup), the borosilicate glass feels solid, and it probably looks better than whatever you’re currently packing your leftovers in. And, as Bryan Quoc Le, PhD, food scientist and founder and CEO at Mendocino Food Consulting, notes, “Glass and stainless steel containers are the best alternatives to plastic ones, since they do not degrade or release any particles.”

    Editorial director Simone Scully has a set, and she has been impressed by them. “These are kind of my new obsession — and I had my doubts. They seemed a little pricey at first and I worried that I wouldn’t find much use for them, but they have slowly become my go-to because they make meal prepping and leftovers so, so much easier,” she says.

    These containers are microwave and dishwasher safe, so you can reheat and rinse without worrying too much about it. “I use them to prep my family’s lunches and snacks, store leftovers, and generally just keep things organized in my refrigerator, which is already small, so space maximization is key,” Scully says. She also appreciates their durability. “They’re glass, and the glass isn’t flimsy,” she says. “These containers don’t fall over easily in the fridge (even with a 6-year-old who is prone to shoving things back in the fridge without regard), and the silicone on the lid makes them easy to unscrew. It’s also genuinely leakproof. I never had any spills (unlike with some other containers I tried).” She concludes: “Overall, these are awesome, and I wish I had way more.”

    Best Stainless Steel Storage for Meal Prep

    Easy Togo 3-Pack Stainless Steel Food Containers With Silicone Base

    $23.99 at Amazon

    Pros

    • Stackable and space-saving
    • Lightweight and durable
    • Comes in three useful sizes

    Cons

    • Not microwave safe
    • Lids can be tricky to align if overfilled

    Key Specs

    • Material: Stainless steel, BPA-free silicone
    • Microwave safe: No
    • Dishwasher safe: Yes (top rack only)
    • Oven safe: Not specified
    • Freezer safe: Yes
    • Capacity: 15.8 oz, 30.4 oz, 33.8 oz

    These stackable stainless steel containers are a smart option for anyone prepping lunches or organizing leftovers without relying on plastic. They’re lightweight, won’t absorb odors, and can go from fridge to oven. They just can’t go in the microwave, for obvious reasons.

    While I now work predominantly from home and the days when I used to faithfully haul a lunch to the office are long gone, I’ve found these containers to be very handy for planning ahead and portioning out leftovers to be served at a later date. The lids are made with transparent silicone, so it’s easy for me to identify the contents, and they have a nonslip silicone shell that ensures that they don’t slide around in the refrigerator. They’re the kind of containers that can take quite a beating, so whether you’re transporting salads to the office or are just accident-prone, these are a foolproof (and plastic-free) bet.

    Best Glass Food Storage for Meal Prep

    Ello Duraglass Meal Prep Containers, Set of 5

    $42.99 at Amazon
    $47.99Now 10% Off

    Pros

    • Leakproof, airtight lids
    • Silicone sleeve for chip and break protection
    • 3.4‑cup size is perfect for proteins, grains, sides

    Cons

    • Smaller capacity for big families
    • Lids are plastic (but BPA‑free)

    Key Specs

    • Material: Tempered glass, with BPA‑free plastic lids, protective silicone sleeve
    • Microwave safe: Yes (glass only)
    • Dishwasher safe: Yes
    • Oven safe: Yes (up to 450 degrees F without lid)
    • Freezer safe: Yes
    • Capacity: Five 3.4-cup containers

    If your container situation doesn’t match your meal-prep ambitions, this set from Ello will help you get it together. The containers are all the same size (so they are easy to stack), the silicone sleeves help prevent chips and cracks, and the locking lids actually hold. “I’ve used one of these for years, and it hasn’t broken yet,” says writer and editor Nicole Bonaccorso. “It’s great for leftovers, but a bit heavy for a school lunch. I love the color choices. One tip: Be sure to take off the silicone exterior from time to time during washing, just to ward off any buildup or mildew.”

    It is worth noting that the lids are plastic, albeit BPA-free plastic, and the 3.4-cup size may be a bit too petite for bigger portion sizes. But we like the way the colorful silicone sleeves give you a little added security, and overall, they’re great for prepping ahead, packing lunches, and just making you feel like you have your life together.

    Best Glass Storage Set

    JoyJolt JoyFul 12 Glass Storage Containers With Leakproof Lids Set

    $36.51 at Amazon
    $42.95Now 15% Off

    Pros

    • Lots of sizes
    • Microwave, oven, and freezer safe
    • Leakproof lids with silicone gaskets

    Cons

    • Full set takes up a lot of space
    • Lids are plastic

    Key Specs

    • Material: Borosilicate glass
    • Microwave safe: Yes (glass only)
    • Dishwasher safe: Yes (lids top rack only)
    • Oven safe: Yes (glass only)
    • Freezer safe: Yes
    • Capacity: Two 9.5 oz, two 12.5 oz, one 13.5 oz, one 16.5 oz, one 20.5 oz, one 25.5 oz, one 31 oz, one 33.5 oz

    If you’ve been meaning to purge your kitchen of mismatched plastic containers and just start fresh, like editor Ally Hirschlag did, this 24-piece set will get you there in one fell swoop. “When I decided to throw away all my plastic containers in an attempt to reduce microplastics exposure, the JoyJolt containers came to my rescue. I was apprehensive about switching to mostly glass because I’m accident-prone, but these guys are virtually indestructible,” Hirsclag says.

    The lead-free borosilicate glass can withstand temperature swings (though the company does not list an upper oven-safe temperature limit for its glassware), the locking lids clamp down tightly, and the size variety covers everything from leftover soup to a handful of chopped herbs. “They’re made of borosilicate glass, which never seems to get too hot in the microwave, but also insulates super well in the freezer. I love the leakproof lids (they really and truly are leakproof), and that you get a nice range of shapes and sizes in the set,” she adds.

    We do wish JoyJolt was a bit more specific about its temperature ranges, and the lids need to be treated somewhat carefully to keep them in top shape (and to ensure they continue to seal tightly). The lids are also made of BPA-free plastic, which may not be ideal for folks looking to avoid the material entirely. But if you’re looking for an affordable way to say goodbye to your plastic food storage, this set is an easy way to do it. “Now I just need about 10 more to support my leftovers habit!” Hirschlag concludes.

    Best Stainless Steel Pantry Storage

    Le’raze Steel Canister Pantry Storage and Organization Set

    $33.99 at Amazon
    $39.99Now 15% Off

    Pros

    • Great for flour, grains, or coffee
    • Lead-free glass shows contents
    • Sleek stainless steel construction

    Cons

    • Not airtight enough for long-term freshness
    • Good for storage only

    Key Specs

    • Material: Stainless steel, lead-free glass
    • Microwave safe: No
    • Dishwasher safe: Yes (but hand-washing recommended)
    • Oven safe: No
    • Freezer safe: No
    • Capacity: 64 oz, 46 oz, 36 oz, 24 oz

    These stainless steel canisters are ideal for dry goods (like oats), pasta, or baking staples (like flour and sugar). While they don’t offer the airtight seal needed for long-term preservation (these have a simple screw-top lid), they’re durable, attractive, and plastic-free, which is great if you want to transition your pantry staples away from plastic bins and bags.

    I like the range of sizes in this set; the larger canisters are ideal for flour and sugar, while I use the smaller ones for more specialized ingredients, like caster sugar or those partial servings of dried rotini I don’t know what to do with. They keep messes to a minimum (anyone who has ever split a plastic bag of dried lentils will know my pain), and the clear strip on the front of each container makes it easy to view the contents at a glance. Or you can be fancy like me and get a label maker. My pantry will never be Pinterest-worthy, but these canisters help prevent it from becoming a total disaster. 

    Best Glass Pantry Storage

    BaoFull Airtight Glass Storage Jars

    $31.99 at Amazon

    Pros

    • Easy to see what’s inside
    • Wooden lid with silicone ring for tight seal
    • Stackable 

    Cons

    • Hand‑washing recommended to keep wood lid looking nice
    • Not suited for liquids or fridge/freezer storage

    Key Specs

    • Material: Borosilicate glass, wood lid with silicone ring
    • Microwave safe: Yes (glass only)
    • Dishwasher safe: No
    • Oven safe: No
    • Freezer safe: No
    • Capacity: Two 25 oz, two 34 oz, two 54 oz

    If your goal is to bring more nonplastic containers into your kitchen, but you still want something that looks nice on open shelves, these glass jars from BaoFull are a solid pick. The borosilicate glass is BPA‑free and strong enough for everyday pantry use, so coffee beans, cereal, nuts, sugar, and pasta all get a tidy home. Each jar comes with a natural acacia wood lid with a silicone seal to keep air out and freshness in (and give them a little added warmth and charm). They also stack neatly, thanks to the shape of the lids, making organization just a little bit easier.

    “These glass food storage containers replaced some of my old plastic ones, and I have to say, it was worth it. The sizes are functional for things like grains and pasta, but they’re also very pretty,” Scully says. She also appreciates another important aspect of their design: the lids. “The seals on the lid are also surprisingly good, which was my biggest worry. I’m not sure if I’d store flour in these, but the seal does seem to actually do its job well. Whenever you open the jars, there’s a very satisfying ‘pop,’ which I personally find very reassuring,” she says.

    These are strictly pantry organizers, and Scully observed that they feel “a little fragile.” However, if you prefer something a little warmer than stainless steel for your decor, these are an affordable and attractive option.

    Best Plastic-Free Wrap Alternative

    Bee’s Wrap Assorted 3-Pack

    $17.09 at Amazon
    $19.99Now 15% Off

    Pros

    • Reusable and compostable
    • Great for sandwiches, produce, and bowl covers
    • Made with organic cotton and beeswax
    • Can be spruced up with more wax when it wears off

    Cons

    • Needs occasional reshaping
    • Doesn’t always give the tightest seal
    • Wax can leave behind a residue at times
    • Shouldn’t be used on hot foods or washed in warm water

    Key Specs

    • Material: Organic cotton, beeswax, resin, and organic plant oil
    • Microwave safe: No
    • Dishwasher safe: No
    • Oven safe: No
    • Freezer safe: Yes (short-term use)
    • Capacity: Small (7 by 8 inches), medium (10 by 11 inches), large (13 by 14 inches)

    Bee’s Wrap is a zero-waste alternative to plastic wrap that actually helps keep your food fresh. Made from organic cotton coated in beeswax and tree resin, these wraps mold to bowls, fruit, or sandwiches using the warmth of your hands. When they wear out, they’re fully compostable or can even be used as a fire starter, according to the company. “This is another I’ve used for quite a while,” says Bonaccorso. “You can even add more wax when it wears off, but it has taken me years to get to that point. I use these over bowls of leftovers, or the occasional can of pumpkin, beans, or tomatoes if I open something and don’t use it all up. I also think these are great to cover up an avocado half.”

    These don’t last forever — Bee’s Wrap indicates that their lifespan is usually about a year, though Bonaccorso finds that they last much longer with proper care — and they have to be hand-washed and allowed to air-dry. Note that part of that proper care is washing them in cool water and avoiding wrapping warm foods (this can melt and remove the wax). But they’re considerably more environmentally friendly than those reams of cling-wrap you’re probably using. Plus, the company even makes a beeswax-free version for those who prefer to stick with vegan products.

    Best for Produce Preservation

    Vejibag Standard Cotton Vegetable Crisper Bags

    $27.99 at Amazon

    Pros

    • Keeps leafy greens fresh longer
    • Made from organic cotton
    • Fully washable and compostable

    Cons

    • Requires redampening

    Key Specs

    • Material: Organic cotton
    • Microwave safe: No
    • Dishwasher safe: No
    • Oven safe: No
    • Freezer safe: Yes
    • Capacity: 11 by 12 inches

    If your crisper drawer is full of good intentions and a healthy dose of guilt, this one’s for you. Vejibag helps extend the life of leafy greens and veggies by creating a slightly humid environment that keeps them crisp, without trapping condensation the way plastic does. Made from organic cotton, it’s washable, reusable, and biodegradable when it’s finally worn out.

    “If you’re like me, and you skip putting your veggies in the plastic bags provided in the produce aisle, this is the tool to keep your lettuce, spinach, and other veggies fresh,” says Bonaccorso. “All you have to do is wet the organic cotton bag, put your veg inside, and plop it in the refrigerator. You won’t have to worry about your carrots getting soft or your greens drying up.”

    Bonaccorso noted that the most annoying thing about the Vejibag is the need to periodically dampen it to retain its produce-preserving qualities. It also has quite a niche purpose. However, while it won’t replace your full food storage lineup, it’s a great tool if you’re trying to cut back on food waste and single-use plastic at the same time.

    How We Tested Nonplastic Food Storage Containers

    using and testing non-plastic food storage
    Everyday Health

    When creating our list of the best nonplastic food storage containers, we focused on options made of glass, stainless steel, silicone, and other plastic-free materials. Then we did what we do best: We tested them the way most people actually use them. Over the course of several months, we stored leftovers, froze soups, packed our lunches, and saw firsthand how they held up in the dishwasher (or sink). We looked at leak resistance, lid fit, ease of cleaning, and how well they nested or stacked in crowded cabinets.

    We also considered guidance from two experts in microplastics and food safety: Lisa Erdle, PhD, ecotoxicologist, microplastics expert, and director of science and innovation at the 5 Gyres Institute, and Bryan Quoc Le, PhD, food scientist and founder and CEO at Mendocino Food Consulting. Their insights helped us prioritize materials that are more durable, safer, and less likely to leach chemicals or shed particles over time.

    What to Look for When Buying Nonplastic Food Storage Containers

    If you’re ready to swap out your plastic containers, here are a few things you should keep in mind:

    Material Matters

    Different materials have their pros and cons. For example, glass is great if you want to put your containers in the oven, and it’s very durable, but it can be heavy, and you run the risk of chipping or breaking it. Stainless steel is virtually indestructible, but it’s not microwave-safe. Food-grade silicone is flexible and freezer-friendly, but things like silicone bags may not lend themselves to super-tidy storage.

    Check for Airtight Seals

    When it comes to containers, a leaky lid or poor seal kind of defeats the purpose. Look for lids that click into place, use tension to seal, or have a silicone gasket that helps keep air out. Silicone storage bags should also seal tightly to prevent leaks.

    Stacking and Storage

    You’ll also want to think about whether the container will play nicely with the rest of your kitchen. Do the pieces stack nicely, or will you have a leaning tower type of situation? Are the lids interchangeable, or are you destined to lose the one you need (inevitably right before you have to leave for work)? Do those storage bags come in the sizes you need, and do you have somewhere to dry and store them?

    Why Should I Switch Away From Plastic Containers if I’m Not Microwaving Them?

    If you’re still holding onto those scratched-up takeout containers, it may be time to reconsider. It’s a common misconception that plastic containers are only risky when heated. According to Erdle, “Even just storing food in plastic containers can cause microplastic migration into food.” That means cold leftovers, fridge staples, and even snacks in a lunchbox can be potential sources of exposure. In fact, a recent study found that participants with higher plastic food container use showed significantly greater microplastic loads, suggesting chronic ingestion over time just from everyday use.


    What makes this more concerning is that plastic containers shed more as they age. “All plastics are susceptible to wear and breakdown over time,” says Erdle. And things like washing, scratches, and repeated use may speed up that shedding, even when you’re not applying heat.

    What Is the Safest Material for Food Storage Containers?

    Experts widely agree that glass, stainless steel, and food-grade silicone are the most inert, nontoxic alternatives to plastic. “Glass and stainless steel containers are the best alternatives to plastic ones,” says Dr. Le. “They do not degrade or release any particles, and they can last indefinitely, which helps sustainability.”

    Not only are these materials safer in terms of chemical stability — many are also more versatile: Glass can go in the microwave and oven (just not right away, as extreme temperature changes can make glass shatter), and silicone can flex to fit tricky storage spots and is great for freezing leftovers. But all of these can, with proper care, potentially be used and reused for years. Importantly, none of these materials is known to shed microplastics with typical use.

    Do Certain Foods Increase the Risk of Microplastic Shedding?

    They can, especially if those foods are hot, fatty, or acidic. These factors can interact with the plastic’s chemical structure, promoting leaching. “Fatty and acidic foods are more likely to interact with the plastic, leading to increased leaching of additives like phthalates and bisphenols,” Erdle explains. Heat amplifies this effect, weakening plastic bonds and accelerating the breakdown process.

    Le agrees: “Acidic foods can react with plastic, and hot foods can increase shedding because they temporarily weaken the plastic’s structure.” Even plastic types that are considered relatively “safe,” like No. 5 polypropylene, can still release particles, especially if the container is scratched, old, or has taken too many trips through the microwave.

    FAQ

    Are glass food containers better than plastic ones?
    Glass containers don’t leach chemicals or absorb stains, which makes them a great alternative to plastic. You can microwave them, stick them in the oven, and they’ll last for years; the tradeoff is that they’re heavier and can be breakable.
    Nope — stainless steel and microwaves just don’t mix. It can spark or damage the appliance. For reheating, stick with microwave-safe glass or silicone containers.
    Yes, and sometimes they’re even better at the task. Plenty of nonplastic containers seal tightly and do a great job of keeping leftovers fresh, especially if they have features like silicone gaskets or locking lids.
    Most are, but to be on the safe side, always check the care instructions. Glass and stainless steel usually go through the dishwasher just fine, but some lids (especially silicone ones with seals) are better off on the top rack or hand-washed to help them last longer.
    You can, but only if the glass is labeled freezer-safe (usually borosilicate or tempered glass falls into this category). If you’re freezing leftovers in a glass container, be sure to leave a little headroom for the food to expand, and never take your container straight from the oven to your freezer or vice versa — extreme temperature swings like that can cause glass to crack.
